Show hintHide hint
Think about their characteristics in the s-plane.
Question 2.
Define dominant pole.
Show hintHide hint
Consider which pole impacts the frequency response the most.
3Question 3.
What defines complex conjugate poles?
- Poles with real parts only

Reflect on the s-plane definition.
4Question 4.
True or False: The dominant pole is the one with the highest frequency.
- True
- False
Show hintHide hint
Think about which pole determines stability.
Question 5.
Given a feedback system with feedback gain approaching significant values, analyze the potential outcomes on pole behavior.
Show hintHide hint
Review pole placement conditions.
Question 6.
Consider a second-order system where both poles shift toward each other due to feedback. Discuss the resulting behavior.
Show hintHide hint
Think about how close poles interact.
